The current battery king, the lithium-ion battery, has been the battery of choice for portable electronics for many years because of its high energy density and decreasing production costs. [+] Read more
However, these market leaders have some significant limitations. Stability and safety are, of course, the most high-profile concerns with these batteries, but size, capacity, and cost are also areas of concern. In the case of electronic vehicles, (EVs), lithium-ion batteries make up a considerable portion of the mass and volume of the EV, require frequent recharging, and they make up a high portion of the cost of these vehicles. The market’s demand for batteries that are safer and that have a higher energy density and lower production cost than current lithium-ion batteries is high. As a result, battery technologies are being improved upon at a rate perhaps never before seen.
ACS materials is at the leading edge of this research with our silicon nanoparticle anode materials.
For example, our Si/C Composite anode material has a higher specific capacity than lithium ion alone, a cycle performance that can reach 1500 cycles, and a capacity retention rate up to 80%. This product has achieved industrialization ton scale, and has been applied in some well-known factories. Batteries constructed with these nanostructure particles have greater structural stability and higher specific capacity than traditional lithium-ion batteries. Silicon nanostructure particle anodes are the future of battery technology.
